This page is about the Russian fighter Yak-1B. For the German version, see Yak-1B (Germany). For the earlier version, see Yak-1.


GarageImage Yak-1B.jpg

The Yak-1B is a rank II Soviet fighter with a battle rating of 3.3 (AB/SB) and 3.0 (RB). It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The Yak-1B is an updated version of the early Yak-1 fighter. The most visible change is the cut-down rear fuselage, providing improved visibility to the pilot. Under the hood, there are many more differences. The new VK-105PF engine provides more power and the twin ShKAS rifle-calibre machine guns have been replaced with a single Berezin UB heavy machine gun.

The Yak-1B is foldered with the Yak-1 and might be skipped by some Soviet pilots in favour of moving on to the Yak-7B. However, this aircraft is well worth the detour: it has delightful flying characteristics and is the best of the short-nosed Yaks available in Rank II. It has very similar performance to the Yak-9T, which in RB is a whole rank and battle rating above it! Those who master the Yak-1B will be well prepared for its descendants, including the celebrated Yak-3.

General info

Flight performance

This improved Yak-1 features, like most mid-war water-cooled fighters, a 1,210 hp engine. It remains sub-par to the German equivalent. However, at the time this plane was fielded, most enemy vehicles were of heavier weight, meaning that it could further utilize the Yak series' excellent manoeuvrability. However, the aircraft is tiered with earlier vehicles in-game, which shifts the performance spectrum of the Yak-1B towards engine power.

Like other Yakovlev fighters, the Yak-1B is a jack-of-all-trades, having good speed, turning ability, roll rate, and climb. Manoeuvring and vertical energy retention are good, so it does not lose much speed in turns and can perform vertical loops effectively. Energy retention in a straight line is decent. It is slightly heavier than the Yak-1 and the turning ability is negligibly worse. However, the new engine makes it one of the fastest aircraft at low altitudes when flying in a straight line. Under 1,000 meters, it can even outrun some 4.3 aircraft like the Pyörremyrsky by a slim margin.

While the climb rate is good, the engine was designed for low altitudes and the performance drops off drastically at higher altitudes. Power loss is noticeable above 3,000 meters and the aircraft will really start to struggle above 4,000 meters. Another issue is its poor high-speed characteristics. Like many other contemporary Soviet aircraft, the wings are made largely of wood and will rip at relatively low speeds compared to US or German fighters. Even before the rip speed is reached, it suffers from some compression issues. The roll compression starts to become noticeable above ~450 km/h IAS and the elevator suffers significantly above ~600 km/h IAS. While it does not compress as badly as the La-5, combat manoeuvring becomes difficult at these speeds. Even if the wings do not snap, the pilot will easily black out.

The engine tends to run hot and without MEC it will overheat at 100% throttle. Dialling down the throttle to about 96% will alleviate the issue with minimal performance impact. Alternatively, using MEC and opening the radiators slightly is enough to run it at 100% indefinitely. Note that the Yak-1B does not have a WEP setting in realistic battles.

Survivability and armour

  • 64 mm Bulletproof glass in cockpit front and rear.
  • 8 mm Steel plate behind the pilot.

Self-sealing fuel tanks are located in the wing roots and wing midsections.

The Yak-1B introduces thick bulletproof glass protecting the pilot and retains the armoured bulkhead behind the pilot's seat from the Yak-1. It is fairly unlikely that the pilot will be knocked out in head-ons as a result. However, the inline, water-cooled engine is very vulnerable to combat damage. The steel plate is enough to protect the pilot from rifle-calibre machine guns from the rear at medium distances, but cannon projectiles and heavy machine guns can still punch right through.

The rest of the airframe has decent constructional strength, though it is still not as hardy as contemporary US aircraft. Cannons and heavy machine guns will do a number on the Yak-1B. The wing fuel tanks are vulnerable to damage in deflection shots and fires will be a common cause of destruction.


Offensive armament

The Yak-1B is armed with:

  • 1 x 20 mm ShVAK cannon, nose-mounted (120 rpg)
  • 1 x 12.7 mm Berezin UB machine gun, nose-mounted (200 rpg)

The Yak-1B is equipped with standard armament for most Yakovlev aircraft: one machine gun and one ShVAK cannon. With 200 and 120 rounds respectively, this is nothing out of the ordinary for this series. It's good against enemy light fighters, but larger aircraft like bombers or twin engine fighters will not go down too easily due to the relatively low burst mass. If forced to engage these tougher targets, try to knock out defensive gunners first and then set the engines on fire with a few accurate bursts.

The ShVAK cannon is an inconsistent weapon in terms of damage, and its main positive attributes are high accuracy and rate of fire. The best belts for it are Default or Armoured targets, though some players use Tracers. Avoid belts containing HEF rounds, as they tend to spark and deal little damage. The Berezin UB heavy machine gun is ironically often more deadly than the ShVAK. The cermet core rounds in the Ground targets belt can rip through enemy aircraft effectively and the Air targets belt is spectacular at starting fires. Air targets is usually the way to go, but feel free to experiment with the others. The ShVAK and Berezin have similar enough ballistics that they can be used together at close to medium range. For harassing targets at somewhat longer distances, use the Berezin in short bursts since it has slightly better ballistics, more ammo to spare, and might start a lucky fire.

If both weapons are fired together, the ShVAK will run out first and the Berezin will be left with around 50 rounds, which is rather insufficient for typical engagements and should indicate that it is time to return to base.

Convergence is generally a non-issue since the guns are mounted tightly in the nose. It is best to either set a relatively high convergence distance (e.g. 600 m) or turn it off entirely.

Suspended armament

Main article: FAB-50 (50 kg)

The Yak-1B can be outfitted with the following ordnance:

  • Without load
  • 2 x 50 kg FAB-50 bombs (100 kg total)

The Yak-1B cannot use the 100 kg bombs available to the Yak-1. The two 50 kg bombs it does have are very weak and there is generally no reason to equip them at all. They need to be dropped almost directly onto ground targets to cause any damage. For ground attack, other aircraft will do a much better job.

Usage in battles

Arcade Battles

The Yak-1B is simply an upgraded Yak-1. The main features that the Yak-1B has over its counterpart is much-improved cockpit visibility, slightly better durability, and a slightly more resilient engine that, unfortunately, still overheats quickly. However, the beauty of the Yakovlev line of fighters lies in two things:

  • Their biggest problem is engine overheating, but this is easily fixed by simply flying between 80%-90% throttle.
  • The Yak's performance is not hindered in the slightest by flying at this engine power.

Due to the above two facts, in AB: fly at 90% power. The Yaks can dogfight just fine at 90%, and will rarely overheat. Even though in Arcade battles all planes get WEP, the WEP on this plane adds almost nothing to its performance while rapidly overheating the engine, thus using WEP is practically unnecessary. If you find yourself in a situation where your aircraft needs more power, throttle up from 90% to 100% power, however, remember to throttle back down to 90% once you can.

Wait for the dogfight to start, then fly in behind a distracted enemy. Shoot in bursts unless tailing a bomber, in which case you will not last very long against their rear gunners unless you are incredibly accurate with the cannon. If your engine begins to overheat, start flying back to your airfield. Otherwise, your engine will give out after the temperature gauge turns red.

To sum up, this is merely a better version of the Yak-1, with similar tactics and strategy. Just remember that Soviet fighter aircraft in general count heavily on its pilot's accuracy, in this case only have two guns!

Realistic Battles

If not using MEC, take off at 100% throttle, then go to 90% after getting above the trees. Upon reaching around 500 m, go to 80-85% throttle. If using MEC, open the radiators somewhat (~20-30%) and turn up the prop pitch (~90%). This will keep the engine cool, allow you to run the throttle at 100%, and also bring out extra propeller thrust for better climb and acceleration. Stay low at all costs! If you climb too high, four things will happen:

  1. You will have run your engine out trying to climb, so your engine has less time before it overheats than usual. (You also don't climb as fast as most other planes, in fact, there are better Soviet aircraft for climbing, such as the MiG-3 and the La-5).
  2. You will be highly visible.
  3. You will have reduced manoeuvrability.
  4. You will easily rip your wings upon trying to dive (The Yak's wings, is made of wood, disappear at about 600 kph).

If you stay below 3,000 m, then you will have more advantages than the enemy, such as:

  1. Better camouflage... harder to spot.
  2. There is almost no chance of ripping wings.
  3. You are already at optimal altitude and speed for manoeuvring.
  4. Enemies easily overshoot you or rip wings attempting to dive on you.
  5. You can trick enemies into flying into the ground (make sure you don't do so yourself!).

If not using MEC, right before entering a dogfight, bring your throttle to 90%. Flying at this reduced throttle setting in Realistic Battles is enough to fight at below 1,000 m (some experienced Yak pilots will even dogfight at 80% throttle!). Immediately after battling it out, bring the throttle back down to 80% (if you don't already have it there). Only in extreme cases use 100% power; however, maintaining that speed tends to overheat the engine quickly.

While the Yak-1B has stellar performance at very low altitudes, it is still a good idea to climb a bit, perhaps to at least 2,000 meters. This gives you more options when an enemy dives in from above. Dodging them with a hard break is a reliable option, and when performed correctly this will sometimes lead to manoeuvre kills, but the enemy can also escape by zoom climbing up, where you will be unable to follow. Essentially, you will be at their mercy unless they become impatient and attempt to dogfight you. Enemies like Spitfires that combine manoeuvrability and altitude advantage will be difficult opponents even if they engage in a dogfight! If you start with some altitude, you can enter a dive to gain speed once they start to get close, then level out and take advantage of the Yak-1B's excellent low-altitude top speed. If the opponent continues to chase you, they will likely run out of bonus speed from the dive and fall behind, neutralizing their energy advantage. If they wisely break off, you can nose up and return to cruising altitude with little energy lost, waiting for another opportunity. Successfully executing this can take a lot of practice, but it is a very useful skill, and not just for Yaks.

The Yak-1B manoeuvres best at around 400 km/h IAS, where its roll and turn rate are optimal. Descending in a turning spiral is a good way to maintain this manoeuvring speed and drag fights down to lower altitudes, where other Soviet aircraft tend to perform better, but obviously review the situation and see if vertical loops, rolling scissors, or other dogfight manoeuvres would be more suitable. The Yak-1B does well in all of these provided that an eye is kept on the speed. Do not go fast enough that the compression becomes an issue, but also avoid getting extremely slow. Take advantage of the landing flaps and strong rudder as necessary when nosing over from a vertical loop, continuing a climbing spiral, or stall climbing.

It is recommended to avoid firing at ground targets due to the limited ammunition available for use against other planes. Remember that you do not reload in mid-air in Realistic Battle, so ammunition conservation is critical while closing the distance with the enemy before firing. Remember, fire only in short bursts to conserve ammunition and avoid jamming the guns. The great thing about the Yak's guns is that they are centre-line mounted. Guns mounted in the propeller shaft mean that you do not have to worry about convergence points, instead lead the target and snipe. The drawback is that you cannot spray the mark with a hail of bullets like most players tend to do. This plane and all the Yaks afterwards are about accuracy and skill necessary to handle this agile plane. Do not commit to head-ons, as the Yak-1B is rather fragile and the burst mass is not enough to reliably win these engagements.

When landing, slow the aircraft to BELOW 300 km/h before lowering the landing gear! Many Yak pilots have ripped their fragile landing gear when descending too fast with them extended. The last thing all Yak pilots should know in Realistic Battles is never to climb higher than 3,000 m (at or below 1,000 m is preferred). The Yak line of fighters was not built to fight at the higher altitudes, and the game is filled with much more capable aircraft in this respect. If you like B&Z or you prefer to climb high, but don't want to use the US or German planes, then use the MiG line or the LaGG/La line of fighters, as they have much better engines. The Yak is a dog-fighter.

Tips from the Aces

  • A Yak pilot can nullify all but the last "Cons" below by staying below 2000 m, and keeping the throttle at 90% for AB, and 85% for RB/SB, or using MEC.
  • If the situation allows, using in-cockpit view can often help with accuracy due to no parallax effect... meaning (hopefully) less of your precious shots wasted.
  • Flaps help with hard turns, but against most opponents, flaps will not be utilized much. Use flaps wisely, since flying at ~90% means a tiny bit less engine power to get back to speed after slowing down due to using flaps. However, don't hesitate to use flaps if the fight depends on it, it is easier to regain speed than to pay for a new plane!
  • Everything learned from the Yak-1B applies to all of the later Yaks. Mastering this plane will repay itself in gold later.

Specific enemies worth noting

  • A6M2 Zeroes: They will out turn you, so try to attack in a shallow dive rather than a turn fight. Energy fighting is also okay because the Zero has poor energy retention and terrible high-speed control and handling. Never dogfight a Zero on its terms and be sure to keep a speed/energy advantage at all times. If things go south, break off and run away - the A6M2 is very slow.
  • P-47Ds: They are much faster than you and are excellent at boom and zoom, so avoid them if possible. If you are caught in a fight, try to energy fight them or turn to fight them.
  • Other Yakovlevs: They are slightly slower, so either keep them occupied with manoeuvres such as the scissors and barrel rolls or energy fight them.
  • Spitfires: They are significantly slower but turn nearly as well as Zeros. Their early Hispano cannons, while inconsistent, are still not good to be hit by, and early models can unleash swarms of rifle-calibre bullets that can ignite the Yak-1B easily. Spitfires also tend to have good climb rates and somewhat better high altitude performance, so seeing them diving from high altitudes is not uncommon. Try to drain their speed and avoid letting them get too close to you. It is difficult to shake a Spitfire from your tail if they have already latched on at close or medium range - running away in level flight can result in taking fire, and dodging will drain your speed and make escape difficult.
  • J21A-1: This Swedish pusher-prop has excellent speed and climb in addition to surprisingly good agility and monstrous firepower. Never commit to a head-on against one, doing so usually results in a direct trip to the hangar. The Yak-1B has the advantage in turn time, but not by a large margin. Dodge their attacks as best as possible and try to bait them into turning. The J21 tends to bleed energy in extended or hard manoeuvres and has issues gaining it back. If you can survive the first few turns, the engagement will be more favourable, making it easier for you or your teammates to knock the J21 out. But never let your guard down.

With the Yak line of fighters, always research the engine and performance modules first! Adding power upgrades will help to lower the overheating of the engine. Afterwards, the aircraft modules can be unlocked in any order according to pilot preference. The Survivability modules are recommended next, as they improve the Yak-1B's manoeuvrability and survivability even more. The Armament modules improve the aircraft only by adding ammo belt types available and allowing the usage of 100 kg of bombs.

Pros and cons


  • Good speed, excellent at low altitude
  • Great agility overall
  • Good structural strength
  • Hard-hitting and accurate 20 mm ShVAK cannon
  • Good rate of climb at low altitudes


  • No WEP in RB/SB
  • Water and oil overheat quickly
  • Low dive speed limit
  • Poor performance above 5,000 m altitude
  • Low ammo count makes this plane reliant on trigger control by the pilot
  • No combat flaps
  • Easily set afire

In-game description

The Yak-1 is a Soviet single-engine fighter of the WWII era. It was the first combat aircraft designed by Alexander Yakovlev's construction bureau and was produced from 1940 to 1944, with a total of 8,700 aircraft built. The Yak-1B variant was a culmination of all 1942 efforts to improve the Yak-1. Work began at TsAGI, where research into improving the water and oil radiators took place between 24th May and 10th June 1942, and work to increase the top speed was conducted between 20th and 26th July 1942. Tactical characteristics of the Yak-1 were significantly improved as a result, leading to Yakovlev's request to the Minister of Aviation to mass-produce a test batch of 20 improved aircraft for combat testing at the front.

However, the improvements looked so good on paper that a test batch was skipped, and a Defence Committee Directive dated 11th August 1942 ordered a new and improved Yak-1 into mass production. Improved armament triggers and a cockpit with improved rearward visibility were welcomed by Soviet pilots and became standard on all contemporary Soviet fighter planes.

Notable pilots

  • Soviet female fighter ace Litvyak was flying a Yak-1B in August 1943 when she was shot down by a group of Bf 109s
  • During the transition from the MiG-3 to the P-39, Pokryshkin flew a Yak-1B and scored several victories in this aircraft.
